Abstract I Fixperimentfi Frove that the entrarmnt of neutrons by Re, which is found among
the, substances usually attached to W, results in the formation of ReI88 with
a spectrum limit of 2 mov and a very small life period of 16.9 hr. One of
the stable tungsten isotopes 0,188) is considered to be the basic source for
the formation of Re188. The beta-spectrum of the w185 plus w188 plus Re188
compowid derived after reneated extraction of Re from W was measured tLad the
results obtained are given in graphs. The decomposition period for 13188 was
established. Three references: 2-USSR and 1-USA (1946-1951). Graphs.

Abstract -s Scientific data are presented regarding the isobaric spins of three
known ~types of Ve-mosons (OV, W, CC- ). All these.particies have almost
identical mass and their spin is apparently equal to 0. It was establish-
ed that allUt -mesons ( pseudo-scalar particles) have uneven ways functions.
No contradicting factors were found to show that all threeIr -mesons do
not represent three different charges states of one ind the as= particle.
all these mesons strongly react with nuclei and this reaction at sufficient-
ly high energies to of no electromagnetic nature. The probability of form-
ing Gy -moo-one-by sta6le gamm-quanta or fast nuolor-i was established for
all three particles,

energies of from 300 - 4000 kev. With respect to resolving power the
instrument was found to be inferior to the ga-spectrometer with im-
proved focus 'Elotron", however, It has a certain advantage over the former,
namely, it utilizes only uniform maguetio fields which mkes it possible
to calculate the form of the gpectral line, spectral sensitivity, luminosity
and 'other properties 6f the irxtrument. Sam results obtained by the appli-
